A couple of years ago, I needed to track a dynamic IP for a couple of months, until a fixed one was organised. I ran this on the client's Linux server with a cron job once an hour: wget -qO- http://ipecho.net/plain | /usr/bin/mutt -s "IP report" j...@jretrading.com I did actually get a bit creative later, and automated the moving of the address from the latest email into my workstation's /etc/hosts file, but I made use of a web server, which you may not have in your own network, and my IMAP processing script was in php. A semi-automatic method would be to save the latest email as a text file, and run a bash script to pick out the address and poke it into the local /etc/hosts. -- Joe
